Bouncing RPM's
Hey all! I posted this questions in the dumb questions thread and didn't get any responses there so I'm asking here. If this isn't the correct thread I apologize, let me know ill move/ delete it.
I'm trying to figure out a issue I'm having with my 2005 Rx8. When I'm in gear the rpm's keep bouncing between 1.5K and 1K in a almost rhythmic pattern, and it only does this when I'm in gear and the clutch pressed in. When its in neutral the idle is just fine without issue, and when I give it gas it runs fine as well, the RPM's only move around if it's gear and the clutch is pushed in. There's no CEL for this issue(not yet anyway) I tried searching for a answer and I'm having a hard time finding it, my research states it seems it could be either the clutch pedal position switch or a bad neutral switch or something else, but tbh i have no clue. Any advice would be greatly appreciated |
Sounds like clutch pedal is out of adjustment and the clutch isn't fully disengaging. The pedal has an adjustment screw, you need to raise the engagement point a little.
A quick way to confirm this: on level ground hold clutch in and put it in 1st. Does the car creep forward? |
Sounds like the clutch safety switch needs to be replaced.

Also ,i have a video of the issue. Please ignore my childish sense of humor. |
Good News everyone!
Turns out Mr_Insulin was correct, it took forever but my car finally through a CEL, P0704, bad clutch switch! Thanks for the advice! |
Same issue
I'm having the same thing going on but I have no idea where the switch is. Recently my safety switch went bad and my friend I bought the car from just hard wired it and now I don't have to press the clutch in to start it up. Not sure if that has anything to do with it though.
